9-7 Reconstruction of Two-dimensional Images beyond Nyquist Frequency using Digital Signal Processing

Abstract

Resolution progress of the two-dimensional image sensor by digital signal processing was performed. Using this method, the two-dimensional image, which has frequency components beyond Nyquist frequency were successfully reconstructed. After the experiment, reproduced images, which have frequency vomponents higher than Nyquist frequency are successfully obtaind. Using this method, it is possible to enhance the resolution of CCD image sensor twice as high at its inherent resolution.
